Pros

Cons

Darth Vader has nothing on this voice changing helmet. While Darth's mask is limited to speaking like James Earl Jones, this helmet from Hasbro modifies your own voice to make it sound like a robotic transformer. At the touch of a button you can channel the Autobot leader's own voice to make the helmet say various catch phrases. And lastly, through the touch of another button you can emit the unique sound of an actual transformer transformation.
